This invention has for it-s object the production of an efiicient low-down self-binding harvester; and it consists in the construction of devices and novel combination of parts,

as set forth.

I have designed in this invention to provide an eficient low-down self-binding harvester, and to this endhave designed devices and combinations of parts, which together 8o compose a practical and well-balanced mecht anism capable of extended use in harvesters of otherv general form. Therefore I do not desire to confine the invention to the exact devices herein shown, when equivalent devices will serve in the combinations devised, yet it is preferred in the manufacture of my harvesters to follow the construction illustrated in the accompanying drawings.

In order to arrange the binder in the de- 9o sired low position, and at the same time to provide for the machine a drive-wheel of suf- 'cient diameter, a right-angle frame is constructed, carrying the drive-wheel to the rear of the line of the grain-platform, the latter extending between said drive-wheel and the draft attachment. In this mannera low rise or elevation of the grain-platform is provided for, the grain in passing to the binder being carried in front of the drive-wheel, and not over roo it, as in many self-binding harvesters now in use; and as the grain-platform is in front of the axis of the drive-wheel it requires to be supported and counterbalanced, and to this end a caster or other wheel-support is provided at the front of the frame, said wheel being located nearly in the line with the drive wheel. A counterbalance spring is usually employed on said wheel-support, and a counterbalaneilig-weight is provided on the rear extension of the frame. For convenience this weight is preferably made in the form of a box-casting to incase the connecting drivegear and to hold tools and other articles. The inclination of the machine-frame is by simple mechanism made adjustable on the axis of the drive-wheel to raise or lower the cutters and steady the saine, and this adjustment is obtained and held by connection with the front wheel-support, and the machine is balanced laterally or upon the drive-wheel line by placing the binder mechanism on that portion of the grain-platform which is outside the line of the track of said drive-wheel, and by constructing the binding mechanism low down or nearly all below the level of the top of the main drive-wheel, this construction bcing easily attained because of the position of the grain-platform relative to that of the main drive-wheel. rl`he weight of the driving mechanism, the binding mechanism, and the machinery designed to aetuate the carrier,buttersickle,and reel is massed near the line of the main drive-wheel, and to this line the main drive-shaft is extended parallel to the side of the main drive-wheel and under the rise of the carrier-platform, this rise affording room below for nearly all the actuating mechanism except the binder.

In order to avoid carrying the grain to the binder when the latter is in operation, the carrier is provided with an automaticallydropping hinged guide-track which drops when the binder starts, so as to permit the rakes to fall below the binder-table, and when the binder stops the track again rises, so that the grain is then carried forward over the rise to the binder. This is effected without stoppage ofthe carrier, which is designed to be in constant action when the machine is in operation. rlhe cut grain is therefore being constantly carried toward the binder; but when the latter is in operation the grain is only carried to the foot of the rise of the grain-platform, where it is massed until the binder ceases its action,when the carrier again comes into action on said rise,earryin g the grain up and over the same. The grain-platforn1,which is in rear of the cutter and finger-bars, is made as thin as practicable. The sprocket-wheels for the chain-carrier at the grain end of the machine are j ournaled in adjustable bearings, whereby the rake-chains may be tightened or loosened when necessary. The chain-rakes have extensions forward of the swivel connection with the carrying-chains tcrminatingin teeth adjacent to the sickle-bar; and because of the low binding mechanism the needle-guard is jointed, and as the needle is retracted said needle guard is shoved to the rear in horizontal or nearly horizontal position by suitable guiding devices. The needle-arm itself is formed with a recess in the front of its compressing portion or shank, said recess alfording play for the binding-cord in its movement between the needle-arm and the bundle while the latter is being compressed and bound.

The binding mechanism is simple and is almost directly connected with the main binder-ojieiating shaft 5G, the latter being provided with an eccentric-bearing which engages a pitman in Connection with a cranked needle-shaft. The needle-shaft, the coinpressor-arms, and the dischargingmechanism are combined with a main binder-wheel having the eccentric-bearin g on one side and on the other a cam-track and cog-segment; and a single shaft carrying the compressing and discharging arms is combined with a trip-arm pivoted 011 the main binder-shaft. ln this manner a single shaft carrying both compressing and discharging arms maybe employed in connection with a lbinder-wheel having devices for moving said shaft to put in operative action, first, the compressing arms, and, secondly, the discharging-arms. The knotter or tying-bill is formed with a tapering channeled curved beak having a lateral rise at its forward end, and provided with a pivoted shouldered tongue extending beyond said beak, and having an elongated notch in its lower edge beveled at its outer end opposite the iirst portion of said risc, whereby the tongue will be automatically opened and closed and will hold the tyingcord automatically until the knot is fully formed, when it will automatically release the cord to allow the knot to be drawn tight.

The reel-shaft is made vertically ad j ustable from a pivotal axis, so that it can be raised or lowered to accommodate it to the height of the grain. It is also made adjustable forward and backward, both of these adjustments being governed by levers within easy reach of the driver on his seat, which is arranged on the rear or counterbalancing extension of the frame, in order that the weight of the driver maybe utilized. lt is preferred to run the reel by chains and sprocket-wheels, and as the reel is'made with a double adjustment, the frame being pivoted to a lever, the chains are passed over guide pulleys or bearings at the angle of the levers, so that whatever be the adjustment of the reel the chains will not be thrown out of driving connection.

The butt-board is preferably made vibratory and adjustable, its upper end being connected to an upright crank-shaft having an arm and connecting-rod extending to the drivers seat, and its lower end being connected to a rotating crank-shaft operated by devices driven by the main shaft.

Other features of the machine will be apparent upon reading the subjoined description.

Referring by letter to the accompanying drawings,`which illustrate a harvester embodying my invention, Adesignates the main frame, which consists of longitudinal timbers a, which constitute the drive-wheel end of the frame, and the cross-bars a' a', forming the platform-frame, and which, as shown inA isV nearly in line with the main drive-wheel- A2 of the machine. The vertical bearingshaft A5 of the caster-wheel A4 is provided at its lower end with a spring L under bearinglug 3, to prevent the transmission of concus-l sions tothe machine in event of the contact of the wheel A with obstructions, and slides in bearings 2 and 3, projecting from the front end of the frame of the machine.

The vertical bearing-shaft A5 maybe hollow or 'provided with a bearing at its upper end for a slotted swivel 4, in the slot 5 of which is journaled a grooved pulley 6, over which a chain 7, connected to lthe bearing 2 at the front end of the main frame,runs and passes down and under a pulley 8, journaled to the front end ofthe top bar Z of the frame of the machine. At its rear end the chain-7 isV connected to the front end of a rearwardlyextending horizontal rod 10, the rear end of said rod 10 being connected to the front end of a chain 11, which chainA 11 runs under a pulley 12, journaled in bearings 13, secured to and rising from the top bar Z, a short distance in front of the rear end of the latter, the rear end of the said top bar Z being connected tothe inner end face of the gearbox,located at the rear end of the main frame of the machine. The rear end of the chain 11 is secured to a lever 14, the latter being fulcrumed on Aa bolt15,which passes through a semicircular perforated rack-plate 16 and secures the latter firmly against the outer face of the top bar Z at the rear end of the latter, so Vthat the lever 14 may be moved forward and back to lower or raise the front end of the' machine when desirable or necessary.'

The front end of the top bar Z is supported by the two inclined brace-pieces 215 and 216, while its rear end is connected to one side of the cord-bar B and is supported thereby. f

The axle A' has secured upon it a double sprocket-wheel D E, consisting of a larger portion D, provided with the teeth D', and a smaller portion E, having the teeth E. 15X is a clutch-section splined upon the said axle and caused to engage with the clutch-section 16X by the coiled spring 17 X, Fig. 3, which bears against the adjacent side of the said double sprocket-wheel. The section 16X is secured to the wheel A2, which turns loosely on the axle A', upon which the wheel A3 also turns loosely. The section 15 can be disengaged from the section 16X, thereby stopping Vthe rotation of the axle by means of the lever 17, the front arm of which is engaged in the circumferential groove of the former section. The said lever is pivoted upon the arm 18, secured to the main frame A, and has its rear arm connected to the lower crank 19 of the vertical double-cranked lever 18X, which is journaled on the bottom and top of the cord-box B, and has its upper crank or handle within easy reach of the drivel-s seat, so that the clutch can be readily operated therefrom.

The large wheel D of the double sprocketwheel D E,Fig. 3, is connected by a sprocketchain 21 with a sprocket-wheel 22, journaled on a shaft 23, mounted in the end wall of the gear-box B, said sprocket-chain 21 passing through openings 24 and 25 in the front wall of said box. y

A hand-lever 26,Figs. 3 and 5,is fulcrumed at its lower end upon the axle A', alongside the sprocket-wheel D E, and extends up between tlie top rail Z and a guard 27, which` limits its forward and backward movements to within easy reach of the driver while in his seat, said hand-lever 26 being retained at its point of adjustment by suitable locking device.

rThe side rails 23 and 29 of the reel-frame are connected at their rear ends to the sides of the hand-lever 26, and the reel-shaft 30 is journaled in bearings at the forward ends of said side rails and projects laterally over the cutter-bar at the front of the' grain-platform.

Between the side rails of the reel-frame'the reel-shaft 30 is provided with a ysprocketwh'eel 31, over which a chain 32 runs, said chain passing over two friction-pulleys 33 and 34, arranged one above the other on the face of the hand-lever 26, and thence down around the sprocket-wheel E on theaxle.'

Near its front lend the reel-frame is provided with a cross-bar 36, and to this crossbar 36 and the side rail 2S of the reel-frame a metal supporting-frame 33 being journaled to the upper rails of the main frame and having its upper horizontal portion vpassing between'the reel-frame and the guard-brace 37. The vertical arm 39 of the pivoted supporting-frame 3S is connected by a horizontal rod 40 to a hand-lever 41, pivoted to the outer face of a perforated plate 42,V secured tothe outer face of a top rail of the frame of the machine near the rear end of thesaid rail, a

guard or guard-brace 37 is secured, a pivoted detent-pin 43 in said lever 41 being em-v ployed to engage either of theholes in said plate 42 to hold the reel-frameat the desired elevation. The reel-frame' is raised and lowered by elevating or depressing the reel-supporting frame' 3S, which is done by moving
